Interesting list. I'm not sure about some of thoses. Riconcito Cubano sources local food? Hot Doug's? It would be cool if they did.
On the other hand, I can prattle off tons of places NOT on that list. I think if you look at the Green City BBQ menu, it would give you a decent idea of the places with the most attention to sourcing local.
Mado, Signature Room, Markethouse, the May St. one that is off of Grand, the Urbans, Big Jones, Lillie Q, Nightwood, Marion St. Cheese; the new place in the Art Institute, those are ones that should be real high on a list.
